Vacuum system using high vacuum coating equipment
The fact that chemical reactions occur in or on the vacuum system of the high-vacuum coating equipment can be used to reduce difficult-to-exclude gases, that is, to convert difficult-to-exclude gases into easily-excluded gases through chemical reactions. Yoshio Murakami proposed to oxidize the remaining hydrogen into water vapor, and then extract the water vapor with a liquid nitrogen cold trap, which is an effort in this regard.
In order to achieve the above object, the present invention provides the following technical solutions: a multifunctional integrated vacuum coating machine, including a vacuum coating machine body, the outside of the vacuum coating machine body is provided with a heat dissipation shell, one of the heat dissipation shells A supplemental air box is fixedly installed on the side, and a supplemental air dust collector and a supplemental pump are respectively arranged inside the supplementary air box. The supplemental air dust collector is in communication with the supplemental air pump. The top of the supplemental air pump is fixedly connected with a through-air supplementary box And the air pipe of the heat dissipation housing, the other side of the heat dissipation housing is fixedly connected with a ventilation pipe, a water trough is arranged between the ventilation pipe and the heat dissipation housing, and a heat dissipation fan and a card are respectively arranged inside the ventilation pipe A groove and a sponge metal mesh, the outside of the ventilation pipe is provided with a gap that matches the sponge metal mesh, and the sponge metal mesh is connected to the water tank, and one side of the sponge metal mesh is fixedly installed with a fixing block, the fixing block A mounting groove is provided on the upper surface of the mounting groove, a limit ring and a spring are arranged inside the mounting groove, the limit ring is located directly above the spring, and the inside of the limit ring and the spring are jointly provided with a movable block penetrating through the fixed block The movable rod corresponds to the slot.
Preferably, a pull ring is fixedly connected to the lower end of the movable rod, and a rubber sleeve is sleeved on the outside of the pull ring.
Preferably, a base is fixedly installed at the bottom of the heat dissipating shell, four grooves are uniformly opened on the lower surface of the base, and a limit groove is opened on the inner side of each groove, and the inner side of the groove The upper surface of the cavity is rotatably connected with a threaded column, the outer side of the threaded column is screwed with a threaded tube, and the outer side of the threaded tube is fixedly installed with a limiting block matching the limiting groove.
Preferably, a foot support is fixedly installed at the lower end of the threaded tube, and an anti-skid pad is fixedly installed on the lower surface of the foot support.
Preferably, the outer side of the threaded column is respectively sleeved with a gear and a gear ring, the gear ring meshes with the gear, and an operating rod is fixedly installed on the outer side of the gear ring.
Preferably, the tooth pitch of the gear is 0.2 mm, and the gear and the threaded column are fixed by welding.
